Over two billion years ago, oxygen released by photosynthetic organisms combined with dissolved iron in the oceans, leading to the formation of massive banded iron formations containing key iron ores. Understanding what mineral pairs with iron depends greatly on whether the context is geological, biological, or industrial.

More than two-thirds of the world's yearly non-fuel mineral production comes from surface mining methods. This highlights the scale of resource extraction. How are minerals obtained by humans? The process is a complex engineering feat involving prospecting, extraction, and processing to turn raw geological deposits into usable materials for countless industrial and technological applications.

Bicarbonate is the dominant form of dissolved inorganic carbon in seawater and most freshwater systems. This crucial ion originates from a variety of interconnected natural sources, including the constant chemical weathering of rocks, ancient mineral deposits, and the metabolic activities of living organisms.
